Dual Inlet Forward Curved Blowers

Dual inlet forward curved blowers deliver more airflow at the same impeller diameter, the classic choice for AHU and commercial air conditioning units. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.

Filters use nameplate maximum values (max airflow at zero static pressure, max static pressure at zero airflow). Check the actual operating point on the performance curve of each model.
